尝试使用 python 和 JSON object 发送 POST 请求并将响应打印到 CSV 文件中

Question

I am trying to send a post request using python script and want to store the response. Below are the two file. Everything is fine when i do the same thing using node.js but when I use a python script instead of node.js it give me this error. Any one know why? not able to find the proper reason why this error pop up.

in request sending first name and last name and in response i will get the full name

Node.js Code (used fastify)

 const conn=require('fastify')({ logger:true }) const PORT=80 const axios = require('axios') //take first and last name as request and in response return full name conn.post('/user',async(req,res)=>{ const user=req.body const fullname=user.first_name + user.last_name console.log(full) res.json(fullname) }) const start_server=async()=>{ try { await conn.listen(PORT) console.log(`server start at PORT ${PORT}`) } catch(error) { conn.log.error(error) process.exit(1) } } start_server()

my Python script

 import requests import json API_ENDPOINT = 'http://localhost:80/user' headers = {'Content-type': 'application/json'} data = { "first_name": "jayanta", "last_name": "lahkar" } r = requests.post('http://localhost:80/user', data) print(r.json())

Error message

{'statusCode': 415, 'code': 'FST_ERR_CTP_INVALID_MEDIA_TYPE', 'error': 'Unsupported Media Type', 'message': 'Unsupported Media Type: application/x-www-form-urlencoded'}

Answer 1

Try:

r = requests.post(url = 'http://localhost:80/user', headers=headers, data=data)

print(r.json())

Answer 2

in the python script:

use json

r = requests.post(url = 'http://localhost:80/user', headers=headers, json=data)

in the node script:

use .send method

const {first_name, last_name} =req.body;
const fullname={first_name, last_name};
res.send(fullname);

here is the answer to your error:

axios.post('url', data, {
        headers: {
            'Content-Type': 'application/json',
        }
    }
